"[Latar Belakang : Iskemia yang terjadi pada lokasi di tubuh mengakibatkan cedera otot reversible sampai ireversibel. Tindakan reperfusi ternyata dapat memperburuk keadaan yang disebabkan oleh kondisi iskemik. Beberapa penelitian terdahulu mencoba mencari teknik proteksi untuk mengurangi efek iskemik reperfusi diantaranya teknik iskemik prekondisi dan teknik hipotermi.Metode : Dilakukan penelitian eksperimental pada kelinci New Zealand White (n=18) dengan satu kelompok kontrol (iskemia) dan dua kelompok perlakuan (preconditioning dan hipotermia). Dilakukan ligasi a. iliaka komunis selama 4 jam, hipotermia sedang (28oC), dan iskemik prekondisi pada masing-masing kelompok. Kemudian kelinci dibiarkan hidup selama 8 jam. Sampel jaringan otot femoralis di ambil untuk pemeriksaan derajat kerusakan otot secara histopatologi.Hasil : Terdapat penurunan secara histopatologi derajat kerusakan otot yang di berikan perlakuan IPC dan perlakuan Hipotermi terhadap kelompok control. Analisis statistik tampak perbedaan bermakna pada sebagian parameter.Kesimpulan : Iskemik Prekondisi dan Hipotermi memberikan efek protektif pada otot dari akibat iskemik reperfusi tungkai bawah akut.;Introduction.Ischemia in certain location in the body could give muscle injury with certain severity from reversible to irreversible. Reperfusion turns out to give more injury than ischemic alone. Previous research try to find the best protective technic to reduce I/R injury including ischemic precondition and hypothermia technic.Method. This prospective, randomized, controlled, experimental animal study was performed in a university-based animal research facility with 18 New Zealand White Rabbit. The rabbits were randomized (n=6 per group) into three groups: I/R group (4 hours of hind limb ischemia and 8 hours of reperfusion), IPC group (three cycles of 5 minutes of ischemia/5 minutes of reperfusion immediately preceding I/R), and hypothermia ( 28oC) together with 4 hours of hind limb ischemia and 8 hours of reperfusion. Muscle tissue were examined based for their histopathological changes.Result.The histopathologic muscle damage score is decreased both in ischemic precondition group and hypothermia group.Although both groups show improvement in histological finding, this finding was statistically significant in few parametersConclusion.

"PendahuluanKeputusan untuk melakukan ligasi Patent Ductus Arteriosus pada saat operasi modifikasi pintas Blalock Taussig pada pasien neonatus dengan duct dependent masih diperdebatkan. Tujuan penelitian ini adalah mencari hubungan antara melakukan ligasi patent ductus arteriosus durante operasi modifikasi pintas Blalock Taussig dengan luaran klinis pada pasien neonatus dengan duct dependent.MetodePenelitian retrospektif ini mencakup neonatus dengan duct dependent yang menjalani operasi modifikasi pintas Blalock Taussig di Pusat Jantung Nasional Harapan Kita antara Januari 2009 sampai Desember 2014. Lama rawat, lama penggunaan ventilator, skor inotropik, kejadian low cardiac output syndrome, kejadian resusitasi, reintervensi dan mortalitas pasca operasi menjadi luaran klinis yang diteliti.HasilTujuh puluh enam neonatus (usia rata rata 11 ± 5,5 hari) menjalani operasi modifikasi pintas Blalock Taussig. Tindakan ligasi patent ductus arteriosus dilakukan pada 31 pasien. Pada kelompok pasien yang dilakukan ligasi patent ductus arteriosus ditemukan angka kejadian low cardiac output syndrome lebih tinggi (32,2 % versus 13,3%, p = 0,047) dan skor inotropik yang lebih tinggi (median 10,1 versus 7,9; p = 0,049). Tidak ada perbedaan yang signifikan antara lama rawat, lama penggunaan ventilator, kejadian resusitasi, kejadian reintervensi dan mortalitas antara kedua kelompok.KesimpulanPada neonatus dengan duct dependent, ligasi PDA durante operasi modifikasi pintas Blalock Taussig berkaitan dengan peningkatan angka kejadian low cardiac output syndrome dan skor inotropik pada periode pasca operasi.

ObjectiveThe question of whether to ligate the patent ductus arteriosus when performing modified Blalock-Taussig shunt surgery in neonates is still a controversy. The aim of this report was to compare the results of ligate versus non ligate of the patent ductus arteriosus during modified Blalock Taussig shunt surgery in neonates with duct dependent.Patient and methodsThis retrospective study included neonates with duct dependent diagnosis who underwent modified Blalock Taussig shunt surgery at Harapan Kita National Cardiovascular Center from January 2009 to December 2014. Hospital stay, intubation time, inotropic score, low cardiac output syndrome event, resuscitation event, reintervention event, and mortality postoperative were studied as clinical outcomes.ResultsSeventy-six neonates (mean age 11 ± 5.5 days) underwent a modified Blalock Taussig procedure. The arterial duct was ligated in 31 patients. Compared with patients in whom the patent ductus arteriosus was left open, patients with a surgically closed arterial duct had a higher incidence of low cardiac output syndrome (32.2 % versus 13.3%, p = 0,047) and higher inotropic score (median 10.1 versus 7.9; p = 0.049). There were no significant difference between length of hospital stay, time to extubation, resuscitation event, reintervention event and mortality between the two groups.ConclusionsIn newborns with duct dependent, ductal ligation during Modified Blalock Taussig shunt procedure is associated with increased incidence of low cardiac output syndrome events and higher inotropic score during the postoperative period."

Introduction. Acute lower limb ischemia may induced ischemia reperfusion injury to the lung and also initiate a systemic inflammatory response syndrome. The aim of this study was to proofed whether IPC and hypothermia of the limb before I/R injury would also attenuates the acute lung injury in rabbit model of hind limb I/R.

Method. This prospective, randomized, controlled, experimental animal study was performed in a university-based animal research facility with 18 New Zealand White Rabbit. The rabbits were randomized (n=6 per group) into three groups: I/R group (4 hours of hind limb ischemia and 8 hours of reperfusion), IPC group (three cycles of 5 minutes of ischemia/5 minutes of reperfusion immediately preceding I/R), and hypothermia ( 28oC) together with 4 hours of hind limb ischemia and 8 hours of reperfusion. Lung tissue were examined based for their histopathological changes. The changes were assessed based on the grading as normal, mild, moderate, and severe damage.

Result. Rabbit treated with IPC (p : 0,001) and hypothermia (p : 0,015) have demonstrated a significant decrease in histopathological features of acute lung reperfusion injury.

Conclusion. Ischemic preconditioning and hypothermia have shown protective effect for the lung from remote ischemic reperfusion injury induced by lower limb ischemia."

Background: Ischemia and reperfusion injury of the lower limb may cause a systemic effect to multi-organ failure. Several studies have been done to prevent distant or remote complication from reperfusion injury, but it is still in debate. This study was conducted to see the differences in renal tubular damage in acute limb ischemia without treatment, treatment of ischemic precondition and treatment of hypothermia.

Methods: An experimental study in 18 New Zealand White rabbits, who performed right common iliac artery ligation for 4 hours and reperfusion during 8 hours, divided into 3 groups: group 1, no treatment as a control; group 2, given the treatment of ischemic precondition before ischemic action: and group 3; given the treatment of hypothermia on the right leg during ischemia. After euthanasia, kidney samples were taken for histopathological examination.

Results: Comparison of renal tubular damage among any group of ischemia with ischemic preconditioning treatment group showed no significant difference (p = 0.092), whereas the comparison between groups ischemia alone with hypothermia treatment group showed a significant difference (p = 0.033).

Conclusion: Treatment of hypothermia may reduce renal tubular damage due to remote reperfusion injury in acute limb ischemia."
